I believe it is $125 more... but here is how we figure it...
In terms of food and drink only:
If you drink 50 bottles of water/soda in a day per room, it is worth it for drinks alone. (If bottles are still $2.50 a piece) This is A LOT but not that many in the heat of summer with 4 or 5 people in a room. And you can take them and then go into the parks so you don't have to buy it in the park.
If you also use the breakfast offerings (which is small and more continental than anything else) instead of going to get breakfast somewhere, you have to offset that breakfast savings... we tend to spend around $20-30 for breakfast for 2. With a growing and hungry toddler who loves breakfast and a pregnant woman, this time would be more I'm sure.
We take advantage of the snacks during naptime. There is also beer and wine from 5-7. So if you take advantage of that, you save on that... its spendy otherwise, lol.
Beyond that, I really like being able to watch the fireworks from there because it is really easy with a kiddo in PJs and I don't feel nearly as bad keeping my DS up past bedtime for them! No crowds to fight back to the hotel.
I can't find a complete listing for you of the offerings and they seem to vary greatly from reviews online... and old reports.
